United States Patent 3,301,596 COLLAPSIBLE CHAIRS Eric A. Eos, Bailey, Colo. 80421 Filed Jan. 5, 1966, Ser. No. 518,807 Claims. (Cl. 297-443) Another object is to provide a collapsible chaise lounge:

which may be readily collapsed into a compact package.

A further object is to provide a chair having a leg rest and arms all of which may be folded, collapsed and telescoped into a relatively small space.

Another object is to provide a collapsible ch-air which is sturdy in construction, simple in operation and economical to manufacture.

With these and various other objects in view, other objects will become apparent as the following description proceeds.

In the drawings, in which like reference characters are used to indicate like parts.

FIG. 1 is a side elevation of a chair embodying the invention in assembled or extended position.

FIG. 2 is a top plan view of the assembled chair.

FIG. 3 is an enlarged detailed cross section taken on the line 3-3 of FIG. 1 showing the arm connection with the back of the chair.

FIG. 4 is an enlarged side elevation of the detail shown in FIG. 3.

FIG. 5 is an enlarged detail taken on the line 5-5 of FIG. 2 showing the position of the inner end of the leg rest with respect to the outer end or the seat of the chair.

FIG. 6 is a side elevation of the seat, back and leg rest of the chair is disassembled condition.-

FIG. 7 is a side elevation of the chair in collapsed or telescoped position. v

FIG. 8 is a side elevation in cross section of the chair in collapsed position taken on a line through the center of the chair.

Referring to the drawings more in detail the side rails of the back part of the chair the lower portions of which function as legs are indicated at 10. These side rails are viewed from the side are arcuate. The radius of the arc is determined by the contour of the back. As shown in FIG. 1 the inside of the back portion is concave.

The back portion consists of spaced parallel slats 11 secured to the upper edges of the back sides rail 10. The seat portion consists of parallel side rails 12 with parallel slats 13 secured to the upper edges of the rails. The leg rest portion has parallel slats 14 secured to the upper surface of the parallel side rails 15. The side rails of the back, the side rails 12 of the seat and the side rails 15 of the leg rest are arcu-ate in profile and the arc of each is the same, as is shown more clearly in FIG. 6.

The side rails 12 of the seat portion are spaced apart to fit inside of the side rails 10 of the back portion and the spacing of the side rails 15 of the leg rest are spaced to fit between the side rails 12 of the seat portion as shown in FIG. 2. In assembled position the seat side rails 12 extend between the back side rails 10. A slat 16 is spaced from the outer slats 11 and is secured to the upper edges of the rails 10; the upper surface of this slat engages and supports the under surface of the seat portion rails 12.

A slat 17 is secured to the under surface of the side rails 10. This slat is spaced from slat 16 and the spacing determines the angle between the seat and the back. As viewed in FIG. 1, the back is concave and the seat convex; this contour is exceptionally comfortable for the occupant of the chair. The -arcuate controur of the leg rest portion 15 is substantially a continuation of the arc of the seat portion and further increases the comfort of the chair as well as facilitating the collapsing of the chair into a compact package.

Secured to the under surface of the side rails 12 adjacent the outer end thereof is a slat 18. The inner ends of the side rails 15 are provided wit-h downwardly extending stops 19 which engage the slat 18 and prevent the leg rest portion from inadvertently being extended further from the outer end of the seat portion as shown in FIG. 1.

A pair of legs 20 are pivotally connected at 21 adjacent the inner surface ofthe outer ends of the siderails 15.

A cross piece 22 connects the legs 20; this cross piece is counter sunk and isfiush with the front edges of the legs in order that the leg rest may be telescoped between the rails 12 of the seat portion as shown in FIGS. 7 and 8.

A pair of arm rests 23 are pivot-ally mounted by bolts 24 on the outside of the side rails 10. The arms are provided with inset portions 25 to increase the resting surface of the arms. The slats 11 secured to the upper surface of the rails 10 which are positioned below the arm rests 23 when the latter are in a substantially horizontal position, as shown in FIG. 1, are longer than the slats above the arms.

The under surfaces of the arms 23 are supported by the upper surface of the slat 26. The slats above the arm rest are shorter than those below to provide clearance for the arm rests when they are pivoted upwardly and around to the position shown in FIGS. 6 and 7.

In the embodiment shown spacers 27 are provided between the arm rests 23 and the side rails 10 to provide further clearance of the inner surfaces of the arm rests from the ends of the slats 11 above the nonmal level of the arm rests and also the slat 17 when the arm rests are pivoted upwardly and around to the collapsed position.

In order to collapse the chair, the legs 20 are folded upwardly between the side rails 15 of the leg rest. The side rails 15 of the leg rest are then moved rearwardly between the side rails '12 of the seat portion. The arm rests 23 are pivoted upwardly and around to the position shown in FIGS. 6 and 7. The side rails 15 of the seat portion together with the leg rest portion is pulled outwardly and removed from in between the side rails 10 of the back portion from the top. With the slats 14 of the seat facing outwardly the rails 15' are moved inwardly with the lower portion of the side rails 15 extending under the slat 17 on the side rails 10. The side rails 15 are moved inwardly between rails 10 to a point where the slat 18 on the seat engages the top slat on the rails 10. In order to trans-port the disassembled chair it is merely necessary to grasp the top slat of the back portion which is abutted against the slat 18 on the seat portion and the sections of the chair will not slide apart.

It is apparent that the uniform arcuate contour of the rails of the back, seat and leg rest portions, enables the chair to be collapsed into an unusually compact package; at the same time the arcuate contour of the rails when the chair is assembled results in a shape that conforms to the contours of the human body when in a comfortably reclining position. The arcuate contour of the side rails of the seat and back portions also result in their being retained at a comfortable angle without the need of offset shoulders, stops, slots or the like.

It is to be understood that this invention is not to be Patented Jan. 31, 1967 v limited by the exact embodiment shown, which is merely by way of illustration and not limitation, as various other forms of the device will be apparent to those skilled in the art without departing from the spirit of the invention or scope of the claims.

I claim: 1. A collapsible chair comprising a seat portion, a back portion, a leg rest portion, spaced parallel side rails on each of said portions, the side rails of said seat portion being spaced to fit between the side rails of the back portion and slida'bly mounted therebetween and the side rails of the leg portion being spaced to fit between the side rails of the seat portion and slid ably mounted the-rebetween, transverse slats on the edges. of said rails the slats on the leg rest portion being of a length to fit between the rails of the seat portion.

2. A collapsible chair as defined in claim 1, wherein the side rails of the portions are arcu-ate in profile and the arc of each rail is the same.

3. A collapsible chair as defined in claim 1 wherein the upper surfaces of the parallel side rails of the b ack portion are concave in profile and the upper surfaces of the parallel side rails of the seat portion and legrest are convex in profile.

4.. A collapsible chair is defined in claim 1 wherein atransverse slat is secured to the under surfaces of the side rails of the back portion and positioned to engage theupper surfaces of the side rails of the seat portion, and another of said slats is secured to the upper surfaces of the side rails of the back portion and positioned to engage the under surfaces of the side rails of the seat portion.

5. A collapsible chair as defined in claim 1 wherein the side rails of each of said portions are arcuate in profile, the arcs of each 'being substantially the same, the upper surfaces of the back portion, being concave and the upper surfaces of the seat portion and leg rest portion being convex.
